Struma operation
The Struma operation was the occupation of a part of northeastern mainland Greece by the Bulgarian army during the First World War between 17–23 August 1916.The Allies planned a large offensive in the Macedonian front for the middle of August to support Romania's entry into the war and pin down as many Bulgarian forces as possible.The Bulgarian high command suspected an impending offensive, and the fighting around Doiran that erupted on 9 August only confirmed these suspicions.The plan on the eastern flank was to seize the Drama-Komotini railway, and this objective was given to the Bulgarian Second Army and the 10th Aegean Division.General Nikolaos Christodoulou did not obey the government and, together with his men, joined the Movement of National Defence that broke out in Thessaloniki.
